Qualifying households can receive up to $600 per kWh, which can cover the vast majority of battery costs.
Commercial & Agricultural Incentives
Federal ITC
Businesses, non-profits, and agricultural organizations qualify for a baseline 30% federal tax credit on the total cost of their solar and battery storage installation.
To secure 2026 ITC levels, projects should be safe-harbored by July 4, 2026. This is typically achieved by having a signed contract and incurring at least 5% of the total project costs.
Domestic Content Bonus (+10% Adder)
You can capture an additional 10% ITC adder by utilizing US-manufactured equipment.
For 2026 projects, OneGrid strategically sources hardware to meet the 50% domestic cost threshold, which can increase your total federal tax credit to 40% or more.
Accelerated Depreciation & MACRS
Commercial entities can take advantage of 100% Bonus Depreciation in the first year, providing an immediate and massive reduction in taxable income.
By pairing the ITC with accelerated MACRS (Modified Accelerated Cost Recovery System) deductions, organizations can significantly shorten the payback period of their investment.By pairing the ITC with accelerated MACRS (Modified Accelerated Cost Recovery System) deductions, organizations can significantly shorten the payback period of their investment.
Non-Profit & Public Sector Advantage
Organizations that do not have federal tax liability (like schools, municipal governments, or non-profits) can utilize Power Purchase Agreements (PPAs). OneGrid installs the system for $0 upfront, and the organization simply buys the solar power at a rate significantly lower than the utility, while the tax benefits are used to buy down the cost of the energy.
